ULN2003APW Description

Short technical summary and product information.

The ULN2003APW from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises seven NPN Darlington pairs, each equipped with common-cathode clamp diodes suitable for switching inductive loads. The device offers a collector current rating of 500mA per single Darlington pair, with the option to parallel pairs for increased current capability.

Key electrical characteristics include a maximum switching voltage of 50V and a peak output current of 0.5A. The input is compatible with CMOS and TTL logic levels, and the output configuration is low-side. The typical delay time is 250ns, with a typical voltage drop at the lowest specified current of 900mV.

This transistor array is housed in a 16-TSSOP package, designed for surface mounting. Its operating temperature range is -40°C to 70°C. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.

The ULN2003APW is specified with a RoHS3 Compliant status and an MSL 1 rating. It is suitable for various industrial and electronic control applications requiring robust output driving capabilities.
